First 'Secret Life of Pets 2' Trailer Takes a Trip to the Vet

The sequel to the 2016 hit animated film finds Max the Jack Russell terrier getting reluctantly dragged into a vet's office. There, he encounters a crazy cat, a frustrated hamster, and another dog grappling with a "bad dog" complex.

The trailer looks just as cute and gently humorous as the original movie. There is one big change behind the scenes, with Max now voiced by Patton Oswalt (replacing the disgraced Louis C.K.).
